Text Similarity
https://api.app.labelf.ai/v2/similarity
We can use labelf's similarity check REST API to evaluate similarities between texts! It uses AI to understand the meaning of the text, which means that two texts can be similar even if they use completely different words/synonyms. A high score in the response implies a high text similarity between texts. We call it using a POST request with your private bearer token together with the texts you wish to perform the similarity check on.
Response format
JSON
Authentication
Yes - Bearer token
Example cURL request

headers = {
'Authorization': f'Bearer {bearer_token}',
}
# Replace top_n with the amount of highest similarity texts to show for each comparison text.
# Replace base_texts with a dictionary of texts
# Replace compare_to_texts with a dictionary of texts you wish to compare to the base texts.
